Description:

See patent 3,004,910 for more information on this notable patent, which the inventor developed to sharpen carbide cutting tools. A 1958 issue of American Machinist (Vol. 102 p. 65) mentions this patent and says, "Anocut Engineering, Chicago, is licensee"; that firm would be the first to introduce a commercial ECM machine. American Machinist & Automated Manufacturing: Jan. 1986-July 1988, Volume 111, page 98, mentions Keeleric's development of electrochemical machining (ECM), and says, "Then in 1959 came the first ECM production machines, and electrochemical machining was on its way to becoming an established metalworking tool." Since then, electrical discharge machining (EDM) has become an important machining technique whereas ECM remains confined to niche applications such as making turbine blades and deburring parts made from hard metals.
